Why are electric trains better than diesel? Powering trains with electricity rather than diesel has several other benefits, according to the authors of Solutionary Rail: The cost of electric locomotive engines is about 20 percent less than diesel locomotive engines on the global market, and maintenance costs are 25-35 percent less than for diesel engines. […]
What is another name for apparent brightness?
What is another name for apparent brightness? The apparent brightness is how much energy is coming from the star per square meter per second, as measured on Earth. The units are watts per square meter (W/m2). Astronomers usually use another measure, magnitude . (Our book calls it apparent magnitude .) What is the difference between […]
What moves faster Earth or Moon?
What moves faster Earth or Moon? Because the Earth rotates faster (once every 24 hours) than the Moon orbits (once every 27.3 days) the bulge tries to “speed up” the Moon, and pull it ahead in its orbit. The Moon is also pulling back on the tidal bulge of the Earth, slowing the Earth’s rotation. […]
What is the dimensional formula for work?
How does the direction of the current effect the magnetic force?
How does the direction of the current effect the magnetic force? The magnetic field produced by an electric current is always oriented perpendicular to the direction of the current flow. Similar to the situation with electric field lines, the greater the number of lines (or the closer they are together) in an area the stronger […]
Does a falling object have negative acceleration?
Does a falling object have negative acceleration? The acceleration due to gravity is ALWAYS negative. Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. The acceleration is negative when going down because it is moving in the negative direction, down. […]
Does an object with a density of 1 float in water?
How do I reduce static?
How do I reduce static? More videos on YouTube Buy a Humidifier. Treat Your Carpets. Rub Dryer Sheets Over Your Upholstery. Stay Moisturized. Wear Low-Static Fabrics & Shoes. Add Baking Soda to Your Laundry. How do you get rid of static cling fast? Static cling can be a frustrating annoyance, but it’s easy enough to […]
How do you prove motion is simple harmonic?
How do you prove motion is simple harmonic? By definition, if a mass m is under SHM its acceleration is directly proportional to displacement. These equations demonstrate that the simple harmonic motion is isochronous (the period and frequency are independent of the amplitude and the initial phase of the motion). Is every oscillatory motion is […]
Are bigger steering wheels better?
Are bigger steering wheels better? Smaller wheels may be more comfortable and take up less space, but the smaller the wheel, the more steering effort required (more so on a car with no power steering). You’ll want to ensure you don’t impair your visibility with too large of a wheel. Why did steering wheels get […]
